Ndi gulu lothandizira Selopt • Meyi 25, 2022
Kodi nsalu za polypneynene ndi chiyani?
Chovala cha Polypropyyylene ndi mawu omwe amagwiritsidwa ntchito pofotokoza chinthu chilichonse chomwe chimachokera ku thermoplastic polyderlene. Pulogalamu yamtunduwu ndi gawo la gulu la polylefin, ndipo si polar komanso pang'ono marystalline. Pafupi ndi polyethylene, polypropropylene ndiye pulasitiki yomwe imapangidwa padziko lapansi, ndipo imagwiritsidwa ntchito kwambiri popanga, ndipo masamba, ndi mitundu ina ya ogula ndi katundu kuposa momwe zimakhalira ndi kapangidwe kake.
Phukusi lamtunduwu lidapangidwa koyambirira ndi American Corportion Phillips Petroleum mu 1951. A Robert Robert Banks ndi J. So Hogan anali akupanga mwangozi polydylene. Ngakhale kuyesera uku kumaonedwa kuti ndichifukwa cholephera, linazindikira kuti gawo latsopanoli limatha kukhala pa por ndi polyethylene mu mapulogalamu ambiri.
Komabe, patatha 1957, komabe, kuti polypfepylene idapangidwa kukhala chinthu choyenera kupanga misa. Mu 1954, katswiri wazamankhwala wa ku Italy Giulio nampambalo adakwanitsa kupanga chinthu ichi kukhala polymer polymer, ndipo morcation a ku Italy adayamba kupanga mankhwalawa pogwiritsa ntchito mankhwalawa.
Polypropylene anagulitsidwa pansi pa dzina la "chimbudzi," ndipo dzinali lidakali chizindikiro cha atondellbaasell. Komabe, ndizofala kwambiri kupeza chinthu ichi chimatchedwa polypropylene kapena "polypro" kwakanthawi.
Ng'ombe za deckity ndi canopy ndi kugwedeza mu nsalu za polypropyylene mu nkhunda
Monga kugwiritsa ntchito kwa polypropylene kunayamba kutchuka kwambiri kwa ogula ndi mafakitale, pang'onopang'ono adazindikira kuti pulasitiki uyu adawonetsanso mawonekedwe ngati mawonekedwe. Nsalu za polypropyyynene ndi gawo lopanda tanthauzo, zomwe zikutanthauza kuti zimapangidwa mwachindunji kuchokera pazinthu popanda kusowa kwa kuluka. Ubwino waukulu wa polypropylene ngati nsalu ndi luso lake lopanda chinyezi; Cholemba ichi sichitha kuyamwa chinyezi chilichonse, ndipo m'malo mwake, chinyezi chimadutsa pali nsalu ya polypropylene kwathunthu.
Izi zimapangitsa chinyontho chomwe chimatha pomwe chimavala chovala cha polypropyylene kuti chitha kusinthika mwachangu kuposa momwe chimakhalira ndi chinyezi chotayika. Chifukwa chake, nsaluyi imatchuka m'malemba omwe amavala bwino pakhungu. Komabe, polypro ali ndi chizolowezi chotenga ndi kufota kwa thupi pakagwiritsidwa ntchito ngati zovala zamkati, ndipo zimasungunuka pamatenthedwe ochepa. Zovala zosungunuka polypro zimatha kuyambitsa kutentha kwambiri, ndipo magaziniyi imapangitsanso kuti zisavute kutsuka nsalu iyi kutentha kwambiri.
Chovala cha Polyproplene ndi chimodzi mwazithunzi zowoneka bwino kwambiri kukhalapo, ndipo ndizovuta kwambiri ndi alkalis ambiri. Kuphatikiza apo, kutentha kwa zinthuzi ndi kotsika kuposa momwe ulusi wopangidwa mwaluso kwambiri, zomwe zikutanthauza kuti ndizoyenera kuvala nyengo yozizira.

Kuphatikiza apo, nsaluyi imagwirizana kwambiri ndi abrasion, ndipo imatsutsanso tizilombo ndi tizirombo tina. Chifukwa cha mikhalidwe yake yowoneka bwino, ndizosavuta kuwumba pulasitiki mu mawonekedwe ndi mafomu osiyanasiyana, ndipo imatha kusinthidwa kudzera pakusungunuka. Phukusi ili silikhalanso lopanda nkhawa.
Komabe, polypro ndiovuta kuvala zitalowetsa, ndipo ndizovuta kuwongolera nsalu iyi. Izi nsalu imatha kuwonongeka kwa UV, ndipo sizimatsatira bwino kapena epoxies. Monga mtundu wina uliwonse wopangidwa, nsalu za polypropyylene ilinso ndi zovuta zoyipa zachilengedwe.
Kodi nsalu za polypropyylene zimapangidwa bwanji?
Monga mitundu yambiri ya pulasitiki, polypro imapangidwa kuchokera ku zinthu zomwe zimachokera ku mafuta a hydrocarborn ngati mafuta a petroleum. Choyamba, ma promer a Monomer amachotsedwa ku mafuta osadukiza, ndipo monomer uyu amathandizidwa ndi makina otchedwa polymerization kuti apange polymerpenne.
Kamodzi malo ambiri a Propeyne mooment ali palimodzi, zinthu za pulasitiki zolimba zimapangidwa. Kuti mupange chisankho chokwanira, polypropylene utoto uyenera kusakanikirana ndi magudumu osiyanasiyana, okhazikika, ndi mafilimu. Izi zowonjezerazi zimayambitsidwa moltte polypro, ndipo kamodzi mankhwalawa atapeza, pulasitiki iyi ikhoza kuloledwa kuzizira kukhala njerwa kapena pellets.
Izi ma pellets kapena njerwa zimasamutsidwa ku fakitale yolembedwa, ndipo amakumbukiridwa. Nthawi zambiri, polypropylene iyi imapangidwa m'matumbo, kapena zitha kuloledwa kuziziritsa mu nkhungu. Ngati mapepala amapangidwa, ulusi woonda uyu amadula mawonekedwe omwe mukufuna ndikusoka kapena ophatikizidwa kuti apange zovala kapena ma diape. Njira zosiyanasiyana zopangira zimagwiritsidwa ntchito popanga polypropylene ku zinthu zosavomerezeka.
Kodi nsalu za polypropylene imagwiritsidwa ntchito bwanji?
Fayilo ya Polypro imagwiritsidwa ntchito mu zovala zomwe zimagwiritsidwa ntchito ngati chinyezi. Mwachitsanzo, pulasitiki yamtunduwu nthawi zambiri imagwiritsidwa ntchito popanga ma strans apamwamba a diapers, omwe ndi zigawo zomwe zimapangitsa kuti khungu likhale ndi khungu. Pogwiritsa ntchito polypropylene ya chigawo ichi, chimatsimikiziridwa kuti palibe chinyezi chidzakhala chokhudzana ndi khungu la mwana, zomwe zimachepetsa mwayi wazopanga za mitanda.
Malo osasunthika a vani-compines apanganso mawonekedwe otchuka chifukwa cha nyengo yozizira. Mwachitsanzo, kusachita kupanga kumeneku kunagwiritsidwa ntchito kupanga zovala zamkati ndi kuphwanya zomwe zidagwiritsidwa ntchito mu m'badwo woyamba wa US Army nyengo yakale (ECWCS). Adapezeka kuti zovala zopangidwa ndi nsalu izi zidasintha kutonthoza asitikali ozizira, koma mavuto omwe nsalu za polypro adapangitsa kuti asitikali a Polypro apangitsa kuti asitikali a United States asinthidwe ku m'badwo waposachedwa wa oyang'anira a Polyst II ndi mibadwo.
Nthawi zina, nsalu za polypropyylene zitha kugwiritsidwanso ntchito kupanga squeewear, koma zovuta zingapo ndi pulasitikizi zapanga mitundu yatsopano ya polyester kwambiri pakugwiritsa ntchito iyi. Pomwe chonyowa chonyowa cha nsalu chiri chofunikira kwambiri kwa Squang'anga, kulephera kusamba nsaluyi ndi madzi otentha kumapangitsa kuti zichotse fungo lochokera ku polypropyylene Squeewear. Kuphatikiza apo, chiwopsezo chazovala zowonongeka ku UV chimapangitsa kuti asakhale chisankho chabwino pa mtundu wina wa uiter.
Kupitilira Padziko Lonse Lapadera, Pulasitiki ya Polypropylene imagwiritsidwa ntchito m'mitundu ingapo yosiyanasiyana. Chimodzi mwazomwe zimagwiritsidwa ntchito kwambiri ndi mankhwalawa ndikumwa udzu; Ndipo zikuluzikulu zidapangidwa kuchokera papepala, polypropylene tsopano ndi zinthu zomwe amakonda polemba izi. Phukusi ili limagwiritsidwanso ntchito kupanga zingwe, zilembo za chakudya, mapangidwe a chakudya, magalasi, komanso mitundu yosiyanasiyana yamatumba.
Kodi nsalu za polypropyylene ili kuti?
China tsopano ndi yotumiza kunja kwa polypropylene. Mu 2016, mafakitale mdziko muno amapanga voliyumu ya plastics yamtengo wapatali $ 5.9 biliyoni, ndipo ndizotsimikizika kuti zojambulazo zidzakhala zokhazikika za tsogolo lodziwikiratu.
Zinthu zambiri zimapangidwanso ku Germany; Dzikoli linatulutsa pafupifupi $ 2,5 biliyoni ya Polypropylene mu 2016, ndi Italy, France, Mexico, ndi Belgium ndiwonso wopatsa mphamvu kwambiri. Mu 2016, United States idatulutsa $ 1.1 biliyoni pazogulitsa za polypro.
Wosewera wamkulu kwambiri mu malonda apadziko lonse lapansi a Polyproplene Wopanga ndi Londellbasell. Kampaniyi imaphatikizidwa ku Netherlands, ndipo imakhala ndi zigawo za opareshoni ku Houston ndi London.
Wothamanga ali mu malonda awa ndi gulu la simu la Sinoc, lomwe limakhazikika ku Beijing, ndi gulu la Petrochina, lomwe limakhazikitsidwanso ku Beijing. Opanga 10 apamwamba a akauntiyi kwa 55 peresenti ya kupanga kwathunthu kwa polypropylene padziko lonse lapansi.
Polypropylene amakonzedwa kukhala nsalu padziko lonse lapansi. Wopanga wamkulu kwambiri wa nsalu za polypro adatha, ndipo mtundu wamtunduwu umasokedwa mu zovala ndi mitundu ina ya nsalu ku India, Pakistan, Indinesia, ndi maiko ena ambiri.
Kodi nsalu za polypdopynene zimawononga ndalama zingati?
Polypropyynene nsalu ya polyplene ikuikidwa mkati mwa bedi lokwezeka
Popeza polypro ndi imodzi mwazipatso zopangidwa ndi pulasitiki, nthawi zambiri zimakhala zotsika kwambiri. Mafakitale ambiri osiyanasiyana amapikisana wina ndi mnzake kuti agwire malonda adziko lapansi, ndipo mpikisanowu umayendetsa mitengo yotsika.
Komabe, nsalu za polypropyylene zitha kukhala zodula kwambiri. Chifukwa chachikulu chowonjezereka pamtengowo chikusowa; Pomwe nsalu za polypropyyylene zogwiritsidwa ntchito zimagwiritsidwa ntchito kupanga zovala zamkati zotentha pafupipafupi, kupita patsogolo kwaposachedwa popanga polyester apanga mtundu uwu wavuta kwambiri.
